Application filed July 7, 1919. serial No. 309,14

residing at Heidenheim-on-the-Brenz, Ger-' many, have invented a certain new and useful improvement in devices for leading away and distributing fiber strips in manufacturing rovings from paper-pulp and the like, for which I have filed applications in Germany March 19, 1917; Austria, January 24;, 1918; Hungary, January 28,1918; Finland, May 29, 1918; Denmark, October 31, 19118; Luxemburg, October 30, 1918; Switzerland, October 26, 1918; Sweden, October 31, 1918; Belgium, December 2, 1918; Holland, November 23, 1918; and Norway,'November 13, 1918, of which the following is a specifica-- tion.

The fiber-strips produced in a web paper or cylinder paper machine are separated from one another by the aid of streams of water or air or by any other manner, so as to give the strips a breadth of about two to six millimeters and from the web or cylinder sieves these strips must be taken off and led away for further operations. The separating and leading away of such fiberstrips from the felt or other surface was accom panied by difficulties which are removed by the present invention. Heretofore the strips were led away by devices, which were arranged at a short distance from the carrying surface, and therefore had the drawback that they were diflicult of access and frequently those strips, which were not led away by the first transporting device were torn. Moreover there was the disadvantage that the devices exerted a certain pull on the wet fibrous material which frequently caused a considerable amount of waste.

According to the present invention the strips are led away from their common movable carrying surface downward in a vertical direction, so that they hang freely, forming a sort of veil, the single strips being in a loose state and solely under the influence of their own weight. From this veil the single strips are led away by a number of transporting devices orrubbing or round ing appliances or spooling means, etc., arranged one above the other, so that no pull whatsoever is exerted on them and there is sufiicient room to guidethe different strips conveniently over to the leading off devices.

In the drawing Figure 1 is a diagrammatical view of a machine constructed accordingto the present invention, The Figs. 2, 3, 4 and 5 show modifications also in diagrammatical views.

In the construction shown in Fig. 1 the paper strips coming from the endless sieve a are taken up by the felt d where the roller 0 rests on the breast roll 6. The felt d transports the fiber-strips over and partly around the guide roll 6 to the delivery roll'g, surrounding this roll to about half of its circumference. The felts return to the roll cby. passing the guide rolls e e 0 A counter roll f presses the felt (Z against the roll 9 which if desired can be heated in any known manner. From the delivery line of the roll 9 the strips, which have been deprived of their water to a considerable extent, hang down vertically, a scrapen h serving for loosening the strips from the roller. At the commencement of the operation the strips 2', which'form a sort of veil, are first led into the waste receptacle m until the paper machine is working regularly, whereupon the paper strips are lead over to the transporting devices for further operations.

In the construction shown in Fig. 1 these transporting devices consist of endless belts k, 70 7%, to which the strips are led in such manner that the first strip is led to the endless belt lc, the second strip to the belt 10 the third strip to the belt 7%, the fourth strip again to the belt is and so on.

The strip veil therefore is distributed in three groups corresponding to the number of transporting belts, the single strips of each group being separated on the endless belt by a space corresponding to two strips. This wide spacing enables the strips to be easily treated in rubbing devices, spooling devices or in any other desired manner.

F or guiding the strips over to the belts k, I0 70 small rollers Z, Z Z may be used which form the starting or front part of the transporting devices and which can be replaced by guiding plates Z Fig. 2, or needles or bars Z Fig. 3. The leading of the different paper strips to the transporting devices may be carried out by hand beginning at; one

side or if desired by streams of air or the like. In the construction shown in Fig. 2 the endless felt d described above is absent. The fiber-strips are taken from the endless sieve, directly to a roller from which they are loosened by a scraper h and pass to a transporting belt a, running over rollers 0. From the last one of which the strips 2' are led downward, thus forming a veil which is distributed on to the transporting belts 79, I0 70 70 70 in a similar manner as described above. p

A more simplified machine is shown in Fig. 3, in which the paper stuff strips are carried from the endless felt a directlyaway by a roller 9 of somewhat larger diameter until they meet a scraper 72. which loosens the strips to form a veil of strips.

In Fig. a a modified machine is shown, in which the endless transporting means are constructed to form well known rubbing or rounding devices 7), p 29 In Fig. 5 a further modification is shown in which the transporting devices are constructed to form reelingdevices q, g 9 by which the strips are wound up to disklike spools. i

I claim: v

1. Device for leading away and distributing fiber-strips from a movable carrier surface comprising a series of transporting means arranged one above the other, their front being disposed approximately vertically under the delivery line of the carrier surface. e e

2. A device for leading away and distributing fiber strips from a movable carvertical with respect to the rier surface which comprises a series of transporting means arranged one above the other and below the point of delivery from the movable'carrier surface, said transporting means being-so disposed that the front of each member thereof is approximately delivery line of the carrier surface.

3. A device for leading away and dis- 'tributing fiber strips from a movable carrier surface comprising a series of transporting means arranged one above the other, their front being disposed approximately vertically under the delivery line of the car-.

rier surface, said transporting means being placed below and at such a distance from the movable carrier. surface that the fiber strips may hang loosely when picked up by said transporting means. i T v at. A device for leading away and distributing fiber strips from a movable carrier surface which comprises a series of transporting means consisting of a guide mem ber and a conveying .member, said series of transporting means being arranged one above the other below the point at which the fiber strip leaves the carrier and the said series of transporting means being disposed so that the front thereof is vertical Withre- 'spect to the line of delivery from the carrier surface.
